It comes and it goes - Dido

Some days I wanna, and some days I don't.
Sometimes I can feel it, and suddenly its gone
Some days I can tell you the truth, and some days I just don't.
Only a change of mood sun goes down someone says something too quick or too soon,
A touch not made, one made too late army's of words can not hope to contain

Then it comes and it goes.
And I have no control.

Some days I can think clear and some days I wont.
Sometimes I can feel it and suddenly its gone
Some days I am strong and some days my skin's broken and thin.
That's when it feels and it takes what it needs and it leaves before I get to know,
Its only a step away moments that army's of words can not hope to contain

Then it comes and it goes.
And I cant make it home.
And there's nothing at home.
And it breaks me when it goes.

Some days I wanna, and some days I don't.
Sometimes I can feel it and suddenly its gone
Some days I can tell you the truth and some days I just don't.
Only a change of mood dream comes out someone does something too quick or too soon,
A move not made, one made too late army's of words can not hope to contain

Then it comes and it goes.
And I seem to hope
And there's nothing at home.
And it breaks me when it goes.
